Greenbuild's Host Committee
USGBC California
The Greenbuild Host Committee is excited to be a part of this year's event, and participate with you this November in Los Angeles, CA! We are looking forward to highlighting the best local community projects that exhibit resilient, low-carbon and healthy design and operations.
About the Host Committee
The Greenbuild Host Committee has a rich and enduring history spanning over 20 years, with thousands of volunteers and industry partners representing various areas of expertise in the green building sector. Volunteering for the host committee is a unique opportunity for local building professionals to gain behind-the-scenes insight into this international event and help make it a memorable celebration for our community.
The Host Committee brings together local sustainability experts and USGBC and USGBC California staff to shape community-focused engagement, programming of local tours, and the overall Greenbuild experience in Los Angeles. Their efforts spotlight resilient design, low-carbon strategies, and healthy building practices throughout the event.
